HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 700, 329 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 700, 329 is 7 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 819, 700, 329 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 819, 700, 329 is 7.
HCF(819, 700, 329) = 7
HCF of 819, 700, 329 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 700, 329 is 7.
Highest Common Factor of 819,700,329 is 7
Step 1: Since 819 > 700, we apply the division lemma to 819 and 700, to get
819 = 700 x 1 + 119
Step 2: Since the reminder 700 ≠ 0, we apply division lemma to 119 and 700, to get
700 = 119 x 5 + 105
Step 3: We consider the new divisor 119 and the new remainder 105, and apply the division lemma to get
119 = 105 x 1 + 14
We consider the new divisor 105 and the new remainder 14,and apply the division lemma to get
105 = 14 x 7 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 819 and 700 is 7
Notice that 7 = HCF(14,7) = HCF(105,14) = HCF(119,105) = HCF(700,119) = HCF(819,700) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 329 > 7, we apply the division lemma to 329 and 7, to get
329 = 7 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 329 is 7
Notice that 7 = HCF(329,7) .
